If the register keyword is present, then taking the address of the
variable is illegal, _whether or not_ the compiler ultimately decides to
turn the varible into a register.

It's in precisely the same class as inline. They're optimization hints
to the compiler. The implementation is under no obligation to honor
any, some, most, or all of such hints.
